摘要：设置造林规格为3m×3m(A)、2m×3m(B)、1m×3m(C)和1m×2m(D)4个水平的密度试验,分析造林密度对黄藤人工林生长与收获的影响。结果表明:萌蘖力、藤丛的母茎长和总茎长均随年龄的增加而增大,随造林密度的增加而递减,密度的不同对6年和14年时的萌蘖力分别造成显著和极显著差异,而对植株母茎长无显著影响,但对14年时藤丛总茎长则有极显著影响;在14年时,林分自疏率随密度的增加而增加,不同密度水平间有极显著差异;林分直径大致随着密度的增加而递减,不同密度间有显著差异,但造林密度减小或增大至一定程度时对直径所产生效应并不明显;单丛产量随密度的增加而减少,受造林密度影响最大,除密度A与B及C与D间无显著差异外,其他密度间均达到显著或极显著差异;藤林总产量随着密度的增大先增加后逐步减少,不同密度间无显著差异,但以密度为3333株·hm-2时的总产量最高。在营建黄藤人工林时,可根据实际情况采用3m×1m或3m×2m密度,从而获得较高的藤产量,便于藤林的经营管理。
The density effect on the growth and yield of Daemonorops margaritae plantation has been analyzed on the basis of experiment of planting density including 3 m × 3 m（A）, 2 m × 3 m（B）, 1 m × 3 m（C） and 1 m × 2 m （D） 4 density levels. The result showed that suckering ability, mean length of mother stem and mean total length of the clump all increased with the age but decreased with planting density; suckering abilities among different density levels were different respectively at the 0-05 and 0.01 level when the stand was 6 and 14-year-old; plant density had no significant effect on mean length of mother stem in all ages but highly significant effect on mean length of rattan clump at the age of 14. The self-thinning rate of 14-year-old stand increased with the density, gaining highly significant difference among density levels; the stand diameter descended with the density approximately and was different at 0.05 level among density treatments but they didn＇ t exert significant effect on diameter when the density increased or decreased to some extent. The clump output reduced with planting density which caused significant or highly significant difference to the clump output under the different density levels one another except level A to level B and level C to level D, indicating the most effect of density on the stand diameter; by comparison, the stand output increased first and then decreased gradually with the density with no significant difference among different treatments but a peak value under the density of 3 333 individuals per hm^2 . Based on these results, the spacing of 3 m × 1 m or 3 m × 2 m should be recommended for the purpose of both higher output and better management of Daemonorops margaritae plantation according to practical situation.
